CHARLES H. SHAV, OF BROOKLYN, NEW YORK, ASSIGNOR TO GUSTAVE WILLEMIN, OFSAME PLACE.

GUARD FOR THE PENDANT-BOWS OF WATCHES.

SPECIFICATION forming part of, Letters Patent No. 278,282, dated May 22,1883.

1' o all whom it may concern:

Be it known that I, CHARLES H. SHAW, of Brooklyn, in Kings county, andState of New York, have invented a certain new and useful Improvement inGuards for the Pendant-Bows of Watches, of which the following is aspecification.

My improvement relates to guards for the pendant-bows of watches.Swivels of watchchains, when applied to pendant bows ofwatchesdestituteot'guards,are apt to slip down under the crowns, wherebyin stem-winding watches the winding is performed. Such accidents are ofcourse objectionable, as injury to the winding mechanism may beoccasioned if the watch-chain should be suddenly pulled while its swivelwere thus engaged with the crown. In watches wherein the hands are setby pulling out the crown and turning it such accidents are vastly moreobjectionable than where the crowns perform no function except inwinding, for they may then effect the shifting of the hands.

It is the object of my improvement to produce a simple and efifectiveguard for preventing the swivel of a watch-chain from engaging with thecrown of a watch to which it is applied.

I am aware that projections from the interier of pendant-bows have beenemployed for this purpose; but they have not-met with great favor,partly because of the expense entailed by their use, and partly byreason of their liability to catch in a pocket and tear it.

My improvement consists in the combination, with the pendant-bow of awatch, of a small loop or ring shaped guard extending downwardly withinthe pendant-bow from the upper portion, and serving to receive theswivel of a watch-chain and hold it in place.

In the accompanying drawings, Figure l is a face view of a watch havinga loop or ring shaped guard combined with its pendant-bow in accordancewith my improvement, and Fig.

2 is a sectional view of the pendant-bow and,

the loop or ring shaped guard.

Similar letters of reference designate correspondin g parts in bothfigures.

Application filed March 13, 1883. (No model.)

A designates the watch; B, the crown on its stem, and (3 its pendantbow. All these parts may be made in the ordinary manner.

D designates the loop or ring shaped guard applied to the upper portionof the pendantbow and extending downwardly into its interior. This guardmay be made integral with the pendant-bow, but will preferably be madeby bending a piece of metal into the form of acircle, with the ends at ashort distance apart, and securing it to the pendant-bow by aband, E.When it is made in this way, the band E may advantageously be fittedbetween its ends, so as to be flush with the interior and slipped overthe pendant-bow to its proper place before the pendant-bow is sprunginto place. The band may then be held in place by friction or may bebound thereon by putting it on while it is hot and the pendant-bow cold,or in any other suitable manner. The band can be secured to the loop orring shaped guard by solder extending between its ends and the interiorof the band. This guard will keep the swivel in place, and yet will notcatch in a pocket.

It is obvious that I may attach the guard to the pendant-bow by twobands attached one to each end of the guard.

I may make the guard oblong instead of round, if desirable.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The combination, with the pendant-bow of a watch, of a loop or ringshaped guard extending from the pendantbow downwardly within theinterior thereof, substantially as specified.

2. The combination, with the pendant-bow of a watch, of a loop or ringshaped guard and a band or hands extending therefrom and surrounding thebow, substantially as specified.
